email issue feature

Email issue features, requires small DB update for search performance issues: db/articlesTableUpdate.sql

I'm not sure how to make the mail widget wider.  I don't see where the #myModalMail div width is declared (I guess somewhere in the bootstrap framework).  The widths for the content are set in percentages so whoever designed it can increase the width and the content should follow.

Also, because it's using the bootstrap framework, I don't know how to properly call the mail widget to close, so I do it manually in js/emailWidget.js line 183:

$('#myModalMail, .modal-backdrop').css('display', 'none');

Those using the framework can look at that and change the line accordingly.
